Thomas Lovejoy

Thomas Lovejoy is chief biodiversity adviser to the president of the World Bank and senior adviser to the president of the United Nations Foundation. From 1973 to 1987 he directed the World Wildlife Fund-U.S., and from 1987 to 1998 he served as assistant secretary for environmental and external affairs for the Smithsonian Institution in Washington, D.C.

Lovejoy predicted back in 1980, that 15-20 percent of all species on earth would have died by the year 2000 (1980:331, SE:252), a prediction which, according to statistician and author Bjorn Lomborg, "clearly did not hold true."
